High cholesterol linked to poor fertility - BioNews

A man's semen count is a marker of his general health, according to the largest study to date evaluating semen quality, reproductive function and metabolic risk in men referred for fertility evaluation. He recently moved as associate professor of endocrinology to Italy's University of Brescia from the University of Padova, where the study took place in collaboration with professor Carlo Foresta, M. Specifically, Ferlin and his colleagues found that about half the men had low sperm counts and were 1. They also had a higher frequency of metabolic syndrome, a cluster of these and other metabolic risk factors that increase the chance of developing diabetes, heart disease and stroke, the investigators reported. A measure of insulin resistance, another problem that can lead to diabetes, also was higher in men with low sperm counts. Low sperm count was defined as less than 39 million per ejaculate, a value also used in the U. All the men in the study had a sperm analysis as part of a comprehensive health evaluation in the university's fertility clinic, which included measurement of their reproductive hormones and metabolic parameters.

Cholesterol: A Gatekeeper of Male Fertility?

According to the Centers for Disease Control and Prevention CDC , high low-density lipoprotein LDL cholesterol, otherwise known as "bad" cholesterol, is a potentially negative health condition that affects more than 70 million Americans. Including when you are younger and thinking about starting a family, as well as when you get older and simply want to stave off heart disease. Even though most people recognize the dangers of high LDL cholesterol on the heart and circulatory system, the CDC also notes that only 1 out of 3 adults have their cholesterol under control. The body needs some LDL cholesterol as a way to maintain nerve cells, but when there is too much LDL, the fatty substance can build up on the walls of the arteries, which can restrict blood flow and can lead to two of the most common causes of death in the U.

Currently, considering cryopreservation of bull semen, there is no clear consensus over the comparability of cryoprotective efficacy of extenders with soybean lecithin and those based on egg yolk. The objective of this study was to prove the use of Low Density Lipoprotein LDL extracted from hen-egg yolk as an enhancing factor for soybean lecithin-based extenders. In total, 35 ejaculates of seven bulls x five ejaculates per bull were collected and cryopreserved at a commercial insemination centre. Modified extender composition effects were assessed on sperm functional parameters motility, plasma membrane, mitochondrial membrane potential and acrosomal integrity after thawing by CASA, flow cytometry and fluorescent microscopy, respectively.
